I have many more poker books that I want to read, but here are my top 5 that I've read and continue to look back on for advice. 

"Positive Poker" by Dr. Patricia Cardner & Jonathan Little

"Elements Of Poker" by Tommy Angelo

"Treat Your Poker Like A Business" by Dusty Schmidt 

"The Mental Game Of Poker" by Jared Tendler

"Caro's Book Of Poker Tells" by Mike Caro

These 5 helped transform my game in a great way. Feel free to share some of yours. 

And as always, best of luck to you all on and off of the felt.
